Abstract

Increased prevalence of DM is accompanied by increased in its various complications include diabetic nephropathy, which can lead to end stage renal disease (ESRD). Urinary albumin-creatinine ratio (uACR) is the gold standard for diabetic nephropathy; however, it has several limitations, including the inability to early diagnose due to the absence of increased level in uACR. Uromodulin is produced by thick ascending limb (TAL) at Henle’s loop and early distal tubule of nephron. Uromodulin will decrease when tubular atrophy occurs in early stage of renal impairment with normoalbuminuria. The aim of this study was to determine the validity of serum uromodulin in type 2 diabetes mellitus (T2DM) in identifying diabetic nephropathy by comparing it with uACR as gold standard. This study was a cross-sectional analytical observational study at Dr. Hasan Sadikin (RSHS) Bandung from June to August 2020. Subjects consisted of 62 patiens with T2DM. Results showed that the serum uromodulin level had a sensitivity of 93.3%, a specificity of 88.2%, a positive predictive value of 95.5%, a negative predictive value of 83.3%, and an accuracy of 91,9% and an AUC value of 0.975. The cut-off point of serum uromodulin in this study was 47.195 ng/mL. In conclusion, serum uromodulin, when compared to the uACR as the gold standard, has good sensitivity and specificity for identifying diabetic nephropathy.

Abstract

Indonesia is one of the countries with the highest multidrug-resistant tuberculosis cases in the world. Rapid molecular test using the Xpert MTB/RIF assay is one of the detection methods for MDR-TB. Early detection of MDR-TB is crucial for early initiation of treatment. However, Xpert MTB/RIF assay only detects the rpoB gene mutations associated with Rifampicin resistance. Recently, WHO recommends the use of Pyrosequencing, a DNA sequencing method that can detect not only the rpoB gene but also katG and/or inhA gene mutations associated with Isoniazid resistance. The aims of this study were to compare the interpretation between the two methods  and to determine the differences in codon mutation position detection of the rpoB gene and mutation detection of the katG and/or inhA gene. This was a cross-sectional comparative observational study on patients ≥18 years old interpreted as RR-TB patients based on Xpert MTB/RIF assay results who had not received MDR-TB drugs at Dr. Hasan Sadikin General Hospital, Bandung, Indonesia. Results showed there were 40 Rifampicin-resistant TB subjects interpreted by Xpert MTB/RIF assay while Pyrosequencing interpreted 30 MDR-TB, 9 RR-TB and one Isoniazid-resistant TB subjects in January - February 2020. The detection of rpoB gene codon mutation position between Xpert MTB/RIF assay and Pyrosequencing methods was not significantly different (p=0.389). Pyrosequencing had detected 27 katG gene mutations, 3 inhA gene mutations, one katG and inhA gene mutation. To conclude, Pyrosequencing can be used for accurate detection of Rifampicin and Isoniazid resistance in MDR-TB. Perbandingan Hasil Interpretasi antara Pyrosequencing dengan Xpert MTB/RIF Assay pada Multidrug-Resistant TuberculosisIndonesia merupakan salah satu negara dengan kasus multidrug-resistant tuberculosis terbanyak. Penegakan diagnosis MDR-TB saat ini menggunakan tes cepat molekular Xpert MTB/RIF assay sehingga pasien segera mendapatkan pengobatan. Namun Xpert MTB/RIF assay hanya mendeteksi mutasi gen rpoB penyandi resistansi Rifampisin. World Health Organization merekomendasikan Pyrosequencing, metode sequencing nukleotida yang dapat mendeteksi mutasi gen rpoB, gen katG dan/atau inhA penyandi resistansi Isoniazid. Tujuan penelitian ini adalah menentukan apakah kedua alat ini memberikan hasil interpretasi yang sama, apakah ada perbedaan deteksi posisi mutasi kodon gen rpoB dan apakah ditemukan mutasi gen katG dan/atau inhA. Penelitian ini merupakan studi observasional komparatif dengan rancangan cross-sectional. Subjek penelitian adalah pasien usia ≥18 tahun yang diinterpretasi RR-TB berdasarkan Xpert MTB/RIF assay di RSUP Dr. Hasan Sadikin Bandung dan belum mendapat pengobatan. Xpert MTB/RIF assay menginterpretasi 40 subjek Rifampicin-resistant TB sedangkan Pyrosequencing menginterpretasi 30 subjek MDR-TB, 9 subjek RR-TB dan satu subjek Isoniazid-resistant TB pada bulan Januari-Februari 2020. Deteksi posisi mutasi kodon gen rpoB antara Xpert MTB/RIF assay dan Pyrosequencing tidak berbeda bermakna (p=0,389). Pyrosequencing mendeteksi 27 mutasi gen katG, 3 mutasi gen inhA, satu mutasi gen katG dan inhA. Kesimpulan, Pyrosequencing dapat digunakan untuk deteksi resistansi Rifampisin dan Isoniazid pada MDR-TB secara lebih akurat.

Abstract

Polycystic ovary syndrome (PCOS) is the most common endocrine abnormality in reproductive-age women, which is characterized by hyperandrogenism, anovulation, and polycystic ovaries. Some evidence suggested that leptin also causes PCOS due to its role in female reproductive system. The physiological function of leptin controls the balance of energy and suppresses the center of appetite. Patients with PCOS maybe underweight, normoweight, overweight, and obese, based on their body mass index (BMI), but obesity is a common clinical situation in PCOS. Obesity occurs when the level of leptin increases but cannot decrease appetite, resulting in leptin resistance. This study aimed to discover the connection between BMI and the level of leptin in patients with PCOS. This was a cross-sectional observational analytic performed in Dr. Hasan Sadikin General Hospital Bandung between April 25 and July 10, 2018. Subjects included 46 PCOS patients who were diagnosed based on Rotterdam criteria by gynecology obstetricians in the hospital. Enzyme-linked immunosorbent assay (ELISA) was used to examine the leptin serum levels. Leptin level increased 74%, mostly in obese patients that comprised 41% of these subjects. Normal leptin levels was seen in 26% of patients, none of them was obese. The Spearman Rank correlation test showed a significant positive correlation between BMI and leptin levels (r=0.644, p=0.000). Hence, a high body mass index in people with PCOS positively correlates with increased leptin level. Korelasi antara Indeks Massa Tubuh dan Kadar Leptin Serum pada Penderita Sindrom Ovarium PolikistikSindrom Ovarium Polikistik (SOPK) merupakan kelainan endokrin pada wanita reproduktif yang ditandai oleh hiperandrogenisme, anovulasi, dan ovarium polikistik. Terdapat beberapa bukti bahwa leptin turut menyebabkan SOPK karena leptin berperan dalam sistem reproduksi wanita. Fungsi fisiologis leptin mengendalikan keseimbangan energi dan menekan pusat nafsu makan. Penderita SOPK dapat memiliki indeks massa tubuh (IMT) underweight, normoweight, overweight dan obese, namun obesitas merupakan gambaran klinis yang umum terjadi pada SOPK. Obesitas terjadi bila peningkatan kadar leptin, namun leptin tidak mampu bekerja menurunkan nafsu makan sehingga terjadi resistensi leptin. Penelitian ini bertujuan mengetahui hubungan IMT dengan kadar leptin pada penderita SOPK. Penelitian ini berbentuk analitik observasional dengan rancangan potong lintang dan dilakukan di Rumah Sakit Umum Pusat Dr. Hasan Sadikin (RSHS) Bandung pada tanggal 25 April–10 Juli 2018. Subjek penelitian sebanyak 46 penderita SOPK yang didiagnosis berdasar atas kriteria Rotterdam oleh klinisi obstetri ginekologi RSHS. Pemeriksaan kadar leptin serum mengunakan metode Enzyme-linked immunosorbent assay (ELISA). Kadar leptin yang meningkat 74% terbanyak pada IMT obese 41% subjek, dan kadar leptin normal 26% tidak ditemukan pada subjek yang IMT obese. Uji korelasi Rank Spearman menunjukkan korelasi positif kuat yang bermakna antara IMT dan kadar leptin (r=0,644; p=0,000). Indeks massa tubuh yang tinggi pada penderita SOPK berkorelasi positif dengan peningkatan kadar leptin.

Abstract

Diabetes Mellitus (DM) is a state of chronically hyperglycemia, which is caused by impaired insulin secretion and function. Thealteration in coagulation system in DM patients served as the basic etiology of macro and micro vascular complication. Platelets are oneof the factors that have a role in the coagulation system and undergo pathological changes in DM patients. Mean Platelet Volume (MPV)is an indicator of platelet function and activation. Larger platelets have more dense and more reactive pro coagulant granules. The aimof this study was to know whether there were differences in MPV between DM patients compared to medical check-up participants atthe Dr. Hasan Sadikin Hospital, Bandung.. The research used analytical descriptive, retrospective data. The inclusion criteria of thisresearch was DM patients and medical check up participants whose serum fasting glucose and two (2) hours post prandial serum glucosewere within the normal range. The data were taken from medical records of DM patients and medical check up participants. The datawere further analyzed with SPSS ver. 15 program using unpaired T-test. In this study, no significant difference between DM patientsand medical check up participants (p>0.05) was found. It can be concluded that Mean Platelet Volume if used as single, can not predictvascular complication in DM patients.

Abstract

Prostate cancer is one of the most common malignancy of males found worldwide including in Asia, and is the second most commoncause of male death in Western countries. Specific cause of prostate cancer is not yet elucidated, but there are several risk factors as well.The diagnosis of prostate cancer is confirmed by digital rectal examination (DRE), prostate-specific antigen (PSA), and a biopsy withtrans-rectal ultrasonography (TRUS). However, the sensitivity of DRE and PSA examinations are low and not good enough to detectprostate cancer. Currently there is a new test called Engrailed-2 (EN2) examination with enzyme-linked immunosorbent assay (ELISA)micro method. The test is simple and uninvasive one. This study is aimed to know the validity of urinary EN2 protein level measurementto detect prostate cancer by analysing. This study was conducted at Dr. Hasan Sadikin Hospital Bandung between November 2012 untilMarch 2013. This study was a diagnostic test with cross sectional design. The subjects of study were men whom suspected to have prostatecancer by DRE, PSA value (≥4 ng/mL) and TRUS biopsy. Urinary EN2 protein levels were measured using ELISA micro method. Statisticalanalysis used Mann-Whitney test, table 2×2 and ROC curve. In this study there are 50 subjects, where the result of positive biopsy forprostate cancer were found on 17 subjects and the negative were on 33 subjects. The study results on cut off value of >0.7 ng/mL gavethe sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 94.12%, 63.64%, 57.1%, 95.5% and 74%,respectively. In conclusion of this study, that the urinary EN2 protein level examination using ELISA micro method has the high sensitivityand moderate specificity, thus these procedure primarily can be used for the screening of prostate cancer.

Abstract

Background Rheumatoid arthritis is the most prevalent form of inflammatory arthritis. One of the key components for its multidimensional outcome is the disease activity, measured by DAS28-ESR. The physical, emotional, and social aspects of RA contribute to the quality of life, and SF-36 questionnaire can be used to measure it. This study aims to ascertain the correlation between the disease activity (DAS28-ESR) and the quality of life (SF-36) in RA patients. Method This study was an analytical, descriptive study with a cross sectional design that took primary data from RA patients undergoing treatment in Rheumatology Clinic of Hasan Sadikin Hospital from February to April 2015. The patient’s data included sex, age, marital status, employment status, educational level, serostatus (RF and Anti-MCV), duration of diagnosis, total number of medications, total number of DMARD, DAS28-ESR scores, and SF-36 scores. The data was analysed with the Shapiro-Wilk normality test, followed by the Rank-Spearman correlation analysis. Result There were 42 subjects, with an average age of 41 ± 12. The ratio between females and males was 20:1, and the majority of subjects (73,8%) had a positive serostatus (RF and/or anti-MCV). The score median of DAS28-ESR was 4,3, with the score median for SF-36 PCS being 39,8 and the score median for SF-36 MCS being 48,2. Based on the the Rank-Spearman analysis (CI of 95%), there was a correlation between DAS28-ESR score and SF-36 PCS score, with the correlation coefficient (r) of -0,577 (p < 0,001), and there was also a correlation between DAS28-ESR score and SF-36 MCS score with r of -0,368 (p = 0,008). Conclusion There was a strong negative correlation between disease activity and physical component of quality of life, and a moderate negative correlation between disease activity and mental component of quality of life, and the two correlations were statistically significant.

Abstract

Objective: To identify auto-antibodies in systemic sclerosis with interstitial lung disease (ILD). Method: This was a descriptive categorical study on auto-antibody profile in systemic sclerosis patients visiting the Rheumatology Clinic of Dr. Hasan Sadikin General Hospital, West Java, and Bandung during the period of January 2018 to December 2019 who were registered in the West Java Systemic Sclerosis Registry. Auto-antibody identification was performed using the Euroline immunoblot assays.Results: Thirty six cases were identified during the study period with most of the cases involved women (n=35, 97.2%). The average age of patients participating in this study was 40 years, with an average duration of disease of 18 months. Diffuse cutaneous systemic sclerosis was found in 22 (61.1%) cases and limited cutaneous systemic sclerosis was observed in 14 (38.9%) cases. Specific autoantibodies were positive in 33 (91.6%) cases, with anti-topoisomerase I as the largest group, positive in 22 (52.9.3%) cases. This was followed by anti-Th/To in eight (15.7%) cases; anti-Ro52 in four (7.8%) cases; anti-centromere in three (5.9%) cases; anti-RNA polymerase in three (5.9%) cases; anti-fibrillarin in three (5.9%) cases; anti-Ku in two (3.9%) cases; and anti-PDGF in one (2.0%) case. High-resolution computed tomography of the lung showed 34 (94.4%) cases with ILD and 22 (61.1%) cases with severe lung fibrosis. Usual interstitial pneumonia was seen in 19 (52.8%) cases and non-specific interstitial pneumonia in 15 (41.7%) cases.Conclusion: Anti-topoisomerase I, anti-Th/To, and anti-Ro52 are the most common autoantibodies observed in systemic sclerosis patients with ILD as the most prevalent feature detected with lung HRCT.

Abstract

The primary pathophysiology of preeclampsia is abnormal trophoblast invasion, vasospasm, and endothelial dysfunction occurring, as well as platelet activation, increased platelet consumption, and the stimulation of the release of new platelets, which affects the platelet indices and immature platelets. This study compared the platelet indices (Mean Platelet Volume=MPV, Platelets Distribution Width=PDW, Platelet Large Cell Ratio=PLCR, and Immature Platelet Fraction (IPF) between preeclampsia and normal pregnancy. This research was an unpaired comparative analytic observational study with a cross-sectional design conducted in the Tangerang District General Hospital from February to August 2020. The platelet indices (MPV, PDW, PLCR) and IPF of preeclampsia subjects (n=33) at Tangerang District General Hospital and normal pregnant subjects (n=38) at Annisa Hospital Tangerang were examined using the Sysmex XN-1000 automatic hematology analyzer. Comparative platelet indices and IPF analysis were carried out by independent T-test or Man-Whitney test. Receiver Operating Characteristics (ROC) analysis was performed to obtain the cut-off value of the platelet indices and IPF to differentiate preeclampsia and normal pregnancy. The platelet indices and IPF were significantly higher in preeclampsia. The mean (SD) MPV was 10.86 (0.9) fL and 10. (0.89) fL, p<0.001; PDW 12.7 (8.7-19.1) fL and 10.85 (8.5-15.7) fL, p<0.001; PLCR 31.96 (7.02) % and 25.06 (6.92) %, p<0.001; and IPF 8.50 (3.10-20.40)% and 2.75 (1.2-9.4)%, p<0.001, respectively in preeclampsia and normal pregnancy. ROC analysis showed that an IPF with an AUC of 0.88 (95% confidence interval (CI) 0.78-0.95) with an IPF cut-off value of >6.5% was a good marker, while the MPV cut-off >10.2 fL, AUC 0.75(95% CI 0.63-0.84), PDW cut-off >11.3fL, AUC 0.77 (95%CI 0.65-0.86) and PLCR cut-off >26.1%, AUC 0.76 (95% CI 0.65-0.85) were good enough markers to differentiate preeclampsia from normal pregnancy. Platelet indices and IPF were statistically significantly higher in preeclampsia. The IPF parameter is a good marker, while the platelet indices can be a pretty good marker to distinguish preeclampsia and normal pregnancy. The IPF parameter and platelet indices can be proposed as a routine examination in pregnancy. Changes in IPF and platelet indices can be early signs of preeclampsia or the development of preeclampsia.
